STOVE-PIPE DAM PER.

SPECIFICATION forming part of Letters Patent No. 300,559l dated June i7, 1884.

Application filed October 11, 1883. (No model.)

To all whom, it may concern: I

Be it known that I, WILLIAM E. BEILMAN, of Buffalo, Erie county, New York, have invented anew and Improved Stove-Pipe Damper, of which the following is afull, clear, and exact description.

My invention consists of an improved means of connecting the pivot-rod for adapting the same to dampers of different sizes.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure lis a plan View of a damper of castiron with my improvements, the damper being tted to a section of stove-pipe. Fig. 2 is Va section of Fig. l on line a' Fig. 3 is a plan View of a sheet-iron damper contrived for theI application of au adjustable pivot-rod, and Fig. 4 is a section of Fig. 3 on lineg/ y.

I make the pivot-rod in two short sections, a., each having a handle or thumb-bit, b, said sections being together a little shorter than a single continuous rod would be for the smallestdamper to which the rod is to be applied, so that vsaid sections willnot quite meet together when applied to the da1nper-plate c or d. rIhese sections of the rod are to be inserted through the holes of the pipe e and in the sockets f of a cast-iron plate, c, or the clips 'g of a sheet-metal plate, said sections being shoved in until the shoulders h bear against the sides of the pipe.` In the cast-metal plate c the inner ends of the said sections of the pivotrod are thento be connected by a loop of wire having the end portions, t', passed through the holes j and hooked over,4as shown, andthe loop portion 7c twisted, as shown, to draw the two sections-of the rod together. The damper c has an opening, Z, at the center to facilitate 4o the fastening of the rod by the wire. When the rod is to be connected to the sheet-metal damper of Fig. 3, it is to be inserted the same way through the pipe and the clips g, said clips being slackened a little by their screws m for the purpose, and then the clips are screwed up tightlyto hold the rod-sections by friction. The sheet-metal damper d is to be stiffened by plates a, which, with the clips g, form clamps,

which add materially to the rigidity of the t dampers by means of the connecting-screws m and the nuts o therefor. It will be seen that the rod may thus be used alike with dampers of different sizes, and that the rod may be effectu-` ually and very simply secured to the damper.

I4 propose to connect the handles or thumbbits b with the outer ends of the pivot-rod by branches p, of small .size and suitable length, to avoid the conducting of much heat to the thu nib-bits, and thus render them safe for handling without danger of burning the fingers.

My improved damper-the one with sheetiron body or plate more particularly-is applicable as well to the `hot-air pipes of furnaces, for conveying air for warming buildings, as to the smoke-pipes leading to the draft,- lue.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- The combinatiomwith the cast-metal damper-plate c, having pivot-sockets f, and a central opening, Z, of the sectional pivot-rod a and a wire-tie, ik, connecting said sections of the pivot-rod, substantially as described.
